Question

state ohms law and express mathematically​

Answer 1

Answer:

According to ohm's law, the current flowing through the conductor is directly proportional to the potential difference applied across its ends, provided that the temperature and pressure remains constant.

Explanation:

V=IR

Answer 2

Explanation:

Ohm's Law states that the current flowing through is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Mathematically it can be represented as:

V= IR

where,

1. V is Voltage in volts
2. R is resistance in ohm
3. I is current in ampere.

Ohm's Law Formula

As an equation, the Ohm's Law serves as an algebraic recipe for calculating the current when the resistance and tue potential difference are known. Likewise, if any two parameters in the equation are known, then the unknown third parameter can easily calculated as follows:

#. To find Voltage (V)

V=IR

#. To find Current (I)

I=V/R

#. To find Resistance (R)

R=V/I

Ohm's Law Applications

1. To determine the voltage, resistance or current of an electric circuit.
2. Ohm's Law is used to maintain the desired voltage drop across the electronic components.

3.Ohm's Law is also used in DC ammeter and other DC shunts to divert the current.
